IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 140,749, dated July 8, 1873; application filed April 9, 1873.

To all whom it may concern:

Be it known that I, Lnwrs B. WHITE, of Norfolk, inthe county of Norfolk and State of Virginia, have invented a new and Improved Plow; and I do hereby declare the following to be a full, clear, and exact description oi' plying a slotted adjustable Wedge betweenthe beam and handles of turn-plows, so that they may both be held solid and without a chance to move out of their respective positions under strain.

Figure 1 is a side elevation. Fig. 2 is a bottom view. Figs. 3 and 4 are detail views of land-side. Fig. 5 is a detail view of wedge E. Fig. 6 is a side elevation of plow-frame from opposite side of Fig. 1. Fig. 7 is a detail view of the adjustable block that connects the handles with the beam.

In the drawing, A represents the frame of a turn-plow; and B, the share to which the front, top, and side of land-side O may be fitted in the usual or any suitable manner. The ands c c are made exactly alike, while the oottom or sole has two reversed ilanges c c that decrease gradually from one end to the other, running out entirely at the latter. They are clamped by screw and nut to the plowframe A, which has slots a a that allow of both a vertical and horizontal adjustment of the land-side, the former to take up wear on the bottom, and the latter to allow the end to be held closely up to the share. By this construction the land-side may be reversed, and much more of the metal utilized than is usual at present. C is the beam which rests upon an arc-faced top, al, of plow-frame, and is attached to handles by an upwardly and downwardly adjustable connection, D, that is slotted and movable on a clamp-screw, d. When the beam is thrown down at the front end to prevent the plow from running too shallow, the rear end, of course, moves up and increases the space betwen the end of beam and handles. As this space varies, it is important and necessary to render the beam rigid by interposing a spacing-block or some other intermediate piece of metal or wood. To answer this purpose, I use a wedge, E, slotted at c, and held by a screw, c, which latter may be easily loosened to allow an adjustment of beam, and readily fastened to secure it rmly after the change of position has been made. In order to secure the handles iirmly and rigidly to the plow-frame, I cast, with the latter, an oblique rear piece, F', having the inner,

parallel, and oblique ianges f f, within which one of the handles Gr rests, and is supported on three sides, while the other is bolted thereto by nuts and screws. The handle, which lies within the groove formed by flanges f f, has a shoulder, g, which rests on the rear end of piece F. To brace and support the oblique piece Ff, I extend a standard, f1, upwardly, i and connect it with the standard a2 by the arc-shaped piece al, upon which is supported the beam, so as to allow of its being turned in a vertical plane.

By this construction I am enabled to hold the handles to plow-frame, so that there is scarcely a possibility that they will be loosened or wrenched out of their true relative position.

The standard a2, instead of rising in a nearly perpendicular line to the beams, like that patented to S. March, March 26, 1867, is so constructed as to recede at an angle of nearly forty-five degrees to a perpendicular let fall from the beam or top piece a1.'

This construction prevents choking, and allows the grass, weeds, or litter to pass easily oli' without resistance.

This standard a2 is then sustained by the brace-standard f1, so as readily to receive seat a1, and help to sustain the weight of beam and the strain at this part of plow. The plowframe F is cut out on the bottom, at f2, to receive the land-side flange, which thus is made to protect it from wear.

Having thus described my invention, what I claim as new, and desire to secure by Letiler ends7 and two similar but reversed botters Patent, istom anges, constructed substantially as and 1. The combination, with beam and handles for the purpose described. connected by an adjustable piece, D, of the LEWIS B.
